6n8846 Water Radiator Core — Cat 120G 3304

This radiator core is a vital part of the engine's cooling system, responsible for dissipating heat from the coolant into the atmosphere. It is constructed to meet OEM specifications, ensuring efficient heat transfer and durability compared to a damaged core that may exhibit leaks or reduced cooling capacity. Operators may notice the engine temperature gauge rising into the red zone, steam escaping from the engine compartment, or coolant loss.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial symptoms of a failing radiator core include visible coolant leaks, a persistent engine overheating warning, or a noticeable drop in coolant level. If left unaddressed, the engine can suffer severe damage from overheating, including warped cylinder heads and damaged internal components. This can lead to extensive and costly repairs.

Installation Tip

Ensure all sealing surfaces are clean and free of debris before installing the new radiator core. Do not overtighten the mounting hardware, as this can distort the core and cause leaks.

Service Note

Inspect the radiator hoses, thermostat, and water pump for wear or leaks when replacing the radiator core.
